One of the most important concepts about energy is that energy can be neither created nor destroyed; it can only be transferred, or converted, from one form to another. They learn that energy transfers can take the form of force, electricity, light, heat and sound and are never without some energy "loss" during the process. Some of the worksheets for this concept are Energy detectives 3 activities, Chemistry energy work answer key, Exploring hydroelectricity, , Topic 5 work and energy, Potential and kinetic energy s, Kinetic and potential energy, Exploring light thermal mechanical and sound energy in. It is helpful to graph the relationship on the classroom board or show students a simulation to demonstrate the relationship, such as The Ramp from PHET Interactive Simulations at http://phet.colorado.edu/en/simulation/the-ramp. Gravity is the force that pulls things down to Earth. Before the rubric, I included the results from our previous lab, which you must use to find the potential and kinetic energies for this lab.
